'05 KJ Sport 2WD, 84800 Miles, changed spark plugs at 36k and 72k, flushed all fluids at 75k. Replaced battery in 2009 because my ex-brother in-law didn't know the proper way to wire up a new stereo head unit.
04 156000 and not one problem only replaced normal wear items, front brakes at almost 100,000, rears at 135,000
Been lifted over 130,000 miles
buddy has an 03 with 186,000 on it about the same no issues with major replacements
Maintenance is the key

2005 3.7L with 135000 miles and only issue I've ever had with it was a locked up rear caliper. Other than that I haven't had one issue. Hasn't stopped on me once since mile 000001!!! Like tommudd said, Maintenance is the key, if you take care of something it will take care of you~
transfer case and rear differential pinion gear seal leaked at about 10k miles (warranty repair, thought the pinion gear had to be replaced twice) replaced crank sensor, cam sensor, brakes only once, on the second set of tires, AC system is non-functioning, just replaced the spark plugs for the first time, all fluids replaced a while ago and need done again, split rubber line from charcoal canister, muffler seam split and i wrapped with ducting and pipe clamps as a temporary fix but is holding up well so i forgot about it until now, original battery split and some miscellaneous tail light bulbs.
Not including wear items(brakes,tires,fluids,and such) or items broken by my stupid actions offroad zero failures for my '02 KJ with 77,000 miles,yes low miles for 9 years old but it sat in storage for 2 years also while deployed.
